SHAFT'FOR VEHICLES.

SPECIFICATION aimin part of Letters Patent No. 649,969, dated May 22, 1900. Application filed November 13, 1899. Serial No. 736,823. (No model.)

T0 (0% whom it may concern:

Be itknown that I, HERMAN H. UOKOTTER, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Shafts, of which the following is a specification,

The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the accompanying drawings, making a part of this application, and in which similar letters of reference indicate corresponding parts, Figure 1 represents a side elevationo'f a pair of shafts, illustrating my invention. Fig. 2 is an under side view of the same. Fig. 3 is a sectional elevation lengthwise of the shaft, showing the double screw-threads. Fig. irepresents a cross-section taken in the plane of the dotted line 4 4 of Fig: 1.

I will now proceed to describe my invention in detail.

A indicates the entire shaft structure.

A A indicate, respectively, the longitudinal shafts.

A indicates the usual and well-known crossbar.

B B indicate the usual T-plates, which respecl'ively connect the adjacent shaft to the cross-bar.

O 0 indicate the customary shaft eyes, each having the shank 0 whereby the eye is nection between the rod and each lug is a screw-threaded connection, the rod being provided at each end with a male screw-thread adapted to engage an interior screw-thread in the adjacent lug. The screw-threads on the rod are respectively right and left hand screws D, so that when the parts are united 'a rotation of the brace-rod D in one direction will serve to simultaneously draw both lugs D D toward each other, and also, of course, the parts to which these lugs are respectively connected, thereby tightening the brace-rod in relation to its connections and stiffening the shaft at the bend. The rotation of the brace-rod D in a contrary direction will ef fectuate a loosening of the same parts. The bend H is further strengthened and the shaft strengthened and the brace-rod D stifiened by means of the following simple and very effective device.

I locate a cross-brace E between the bracerod D and the central portion of the bend H of the shaft, and this brace is connected to the brace-rod D and the shaft substantially as follows: There is an eye orsleeve E embracing the.brace-rod D, and to this one end of this cross-brace E is connected by a screw or other connection. The other end of this brace is connected to a clip E --that is, to the clip-bar E which latter, in conjunction with a clip E firmly embraces the shaft. The rods of the clip E pass through the clip-bar E and are secured in place by the usual screwsecurely bolted to the rear end of the shaft. Each shaft has the usual curve H atits rear nuts E".

The brace-rod D is separable from the lugs the braces separable and adjustable.

portion. I

My invention in general has for its object the bracing and strengthening of the shaft at and in the vicinity of the curve by bracing structures, which I will hereinafter describe. Another object of my invention is to render One of these braces consists of an iron (or other metal) rod D, extended across the space between the bend H of the shaft. The forward end of the rod D is received in a lug D located on the plate B, and is formed in one with the latter, and the rear end of the rod D is received in a lug D located on the shank of the shaft-eye, and is formed in one with the latter. Not only this, but the con- D and D and the latter, with their adjacent portions of the shaft structure, are adjustable with reference to the brace-rod D, the latter being capable of being shortened or lengthened in relation thereto; also, that the cross brace-rod E is separable from certain portions and adjustable in the direction of the length of the shaft.

It is to be observed that the lugs are specially formed so that at one end they melt or disappear into the surface of the part, (T- plate or shaft-eye shank,) to which they are connected,thus not only saving metal, but presenting a much neater appearance to the eye.

The entire structure is very strong and can be kept as rigid as desired, and the parts can be kept not only rigid, but can be prevented from rattling.

When desired, the eyes 0 instead of being as shown may be what is known as quickdetachable ones. The conformation of the eye itself is not material to the present invention. The eye may be of any desired form or kind.

What I claim as new and of my invention, and desire to secure by Letters Patent; isj

1. In a pair of shafts, the combination of theshaft cross-bar,-T-p1ate, shaft-eye shank," the lug D? of the T-platej, thelug D32 of: the. 1;
